I started back at work on Monday and I'm just not pumping enough. I don't think it's a supply issue because I've had plenty of milk common for second baby. I tried drinking a lot of water and looking at a pic of DD while I pumped. I pump 3x a day for about 25 mins each to replace the 3 missed feedings. She's 3mo and takes 4-oz bottles and each day I have come a few ounces shy of the 12 oz I need for the next day's bottles. Any suggestions/advice/ideas would be so helpful!
